Threatened and Endangered Species <br />State -of -the -art mining techniques (pillar and panel widths, rate of coal development and <br />extraction, mine method, determining angle of draw, etc.) would be used to control <br />subsidence. No mining - related surface disturbance ( i.e., M D W s and roads — <br />n o t including subsidence) would occur within 200 feet of greenback cutthroat trout <br />occupied habitat, as measured from the normal high water mark, without a written finding <br />from the Authorized Officer. These techniques would provide for maximum coal <br />removal while protecting the values associated with the threatened greenback cutthroat <br />trout habitat. <br />• Adequate sediment control devices, such as silt fences or straw wattles composed of <br />native substances or other effective BMPs, would be placed down slope from the pads <br />and access roads to prevent potential sedimentation effects to West Terror Creek. <br />In order to ensure that BMPs relating to the control of sediment from disturbed sites are <br />in place and functional, lessee shall, during major runoff periods, use an independent <br />contractor to inspect the lessee's well pad sites and access roads within the Terror Creek <br />watershed. The independent contractor shall contact lessee, USFS, and the BLM (970- <br />240 -5300) within two business days of discovering sediment control measures that are <br />missing or non - functional. Lessee will have three business days to correct the problem. <br />Ineffective measures would be redesigned and replaced after consultation with USFS and <br />BLM. For each year that lessee operates under this BA, lessee shall submit the compiled <br />monthly inspection reports to BLM UFO by September 30. In the event new sediment <br />control methods are identified or current practices are not working as intended, adaptive <br />management will be used to implement methods that are effective at eliminating offshe <br />movement of soils and sedimentation into resident streams. <br />• At any time during drilling activities, until successful reclamation or continuing into the <br />future, the point of access to temporary roads shall be blocked with gates to prevent <br />vehicles, including Off - Highway Vehicles (OHVs), from using them. Signs identifying <br />the road closure shall be placed at the barricades. <br />To prevent mortality of GBCT due to pumping from the East Fork of Terror Creek, the <br />conservation measures are defined as: pumping during the June and July period would <br />require the use of a screened pump intake, with a maximum '/4 inch size mesh. For the <br />August through September period, when GBCT fry would be present in the stream, pump <br />intakes would be screened with no larger than 1/ 16th mesh screen. The screen would not <br />be confined to just the pump intake, but must cover a larger area, such as a cylinder or <br />box design which has at least 5 times the surface area of the pump intake. Bowie must <br />submit the final design for this screening fixture to the USFS and BLM fisheries biologists <br />for their approval. <br />• During the June through September period, if the flows in East Terror Creek drop below <br />the ten year mean monthly flow for October (1.0 cfs), lessee will not pump water from <br />the East Fork of Terror Creek. <br />To prevent impacts to GBCT fry and fingerlings, pumping would not take place during <br />the base flow (low flow) periods of the year — October through March. <br />2 <br />
